Capillary tube systems do not control evaporator superheat or evaporator pressure. They are usually used where the heat load on the evaporator is relatively constant; however, any liquid refrigerant ...

Capillary tubes are generally used as the metering device on small, fractional-horsepower refrigeration systems. Charging these systems with refrigerant requires a different procedure than those ...
